2025-12-02

• [Stefan] Auto delete branches on merge?
  • Decision: Yes, Nina will adapt configuration
• [Nina]
  • Eclipse Theia v1.67.0 release postponed to Wednesday, 2025-12-10
    • Endgame Plan for 1.67.x
  • Update to trusted NPM publishing (OIDC auth) was completed
    • Details sent via theia-dev mailing list, see message from November 27, 2025: https://www.eclipse.org/lists/theia-dev/msg00320.html

2025-11-27

• [Nina]
  • Eclipse Theia v1.67.0 release is planned for this Thursday, 2025-11-27
    • Endgame Plan for 1.67.x

2025-11-18

• [Nina]
  • Release 1.66.200 promoted to stable
    • issues on Ubuntu with Wayland (graphical display server protocol), needs to be addressed on the long run as this becomes default
  • Skip December Release? - Stretch 1.68.x Release to January 29, 2026
  • NPM token management: Existing classic tokens will be revoked on December 9, 2025 (was extended)
    • preparation work done for trusted workflow with OIDC auth, migration expected to finish this week
    • In the course of this, I would like to update the Publish Access of the theia packages to the recommended Require two-factor authentication and disallow tokens (recommended) (currently it does not require 2FA). For manualy publishing, 2FA is then required for the npm account from then on (e.g. for initial publishing of new packages)

2025-11-11

• [Nina]
  • Release updates 1.66.x: Theia IDE 1.66.x Preview Testing ongoing, promotion to stable expected tomorrow, Nov 12th (EOD)
  • NPM token management: Existing classic tokens will be revoked on November 19, 2025
    • Has anyone looked into it yet? Otherwise we can do it this week.

2025-11-04

[Nina]: Release updates 1.66.x

• Theia IDE 1.66.x Preview Testing
• 1.66.1 endgame plan

2025-10-28

• [Stefan] Approach for localization of "rich" content

2025-10-21

• [Nina]
  • License check workflow
    • Now runs only for dependency updates
    • Added details to the Review Checklist, i.e. running the license check in review mode locally when new dependencies are added. We also do this periodically after each release for general dependency upgrades, but it would be great to include it as part of PR review cycle as well.
  • l10n/localization:
    • Thanks to @pisv for the significant effort in localizing, especially all the AI-related packages (Reference: pisv’s localization PRs)
    • Reminder: Please follow the localization requirements from the Coding Guidelines
    • Suggestion: add a bullet point to the Review Checklist if no one objects; Edit: add to PR template as checkbox and create issue for an automatic detection of un-localized string with the GH Copilot (Stefan offered to take a look with low prio)

2025-10-14

• [Matthew] Code Review by AI https://github.com/EuphoricRPG/euphoric/pull/19

• [Nina]
  • Release update 1.65.1
    • Theia IDE 1.65.x Preview Testing
  • updated built-in extensions to 1.104.0 - publishing to open-vsx is missing due to invalid access token

• [Simon] Flatpak build? How do we decide what to support? (#360 & #527)

  • 1.64.2 endgame plan
  • 1.65.1 endgame plan
  • Theia IDE 1.65.x Preview Testing

2025-09-23

• [Jonas]: Please contribute/update roadmap
• [Stefan]: npm supply chain attacks
  • when and how to upgrade dependencies
  • publishing permissions
  • provenance attestation
    • Update: opened a ticket to ensure this for regular releases: https://github.com/eclipse-theia/theia/issues/16314
• [Nina]: planning to update built-in extensions to 1.104.0 (from 1.95.3) for upcoming release, to ensure test phase for next CR (see https://github.com/eclipse-theia/vscode-builtin-extensions/pull/138)
  • Update: The extension update is not included in the upcoming release because I underestimated the time required for license reviews and the publishing process. This is now clear, and it should not be an issue for the planned future regular updates (quarterly, after each CR).
• [Nina]: upcoming release 1.65.x planned for Thursday September 25, 2025: https://github.com/eclipse-theia/theia/issues/16293
